Abstract
A medical device for indicating a chest compression depth, including a first electrode assembly structured to be disposed on a chest of a patient, a second electrode assembly structured to be disposed on a back of the patient, and a processor configured to determine a chest compression depth as a proportion of chest height based on a first impedance measurement between the first electrode assembly and the second electrode assembly when the chest is not compressed and a second impedance measurement between the first electrode assembly and the second electrode assembly when the chest is compressed.
